There is a problem however. If the title contains a " character, the tooltip on the links will corrupt the HTML, since the title attribute on the links is not escaped. At the same time, the href attribute is not enclosed in "-s, so this is not HTML compliant also.
Easy to fix, in the "tmpl" directory of the module (mod_articlelist), you can find a
"default.php" file. The problem is on line 7, this is the correct version (not sure if it eill come through correctly, but I hope):
" href="">title; ?>
Other than this, it is a perfectly good plugin - and it is completely free...
